REGENERATIVE GAS-FURNACE.

SPECIFICATION forming part of Letters Patent No. 392,897, dated November 13, 1888.

Application filed June 5, 1988. Serial No. 276.130.

in Regenerative Gas Furnaces, of which the following is a specification. 9,

This invention relates to a regenel'ative gasfurnace of that clase in whlch'the airgsupplied for combustion is heated before it is mixed with the products of combustion, so as to produce the more perfect combustion of the fuel; and the invention consists of a regenerative gasfurnace in which a primary series of flues for heating the air is arranged intermediately between the fines for conducting off the products of combustion, the first series of air-fines supplying heated air to the fuel on the furnacegr'ate, while a second series of air-flues,which is also arranged between heating-flues, supplies air to the combustion-chamber of the furheat from the same, the air being drawn .in

through bottom fines below the ash-pit and supplied by an upwardly-extending rear flue having eduction-channels to the rear part of the furnace, so as to supply a third current of heated air and produce the combustion of the still unconsumed firegases at a point above the emission-channels for the second currentof air, the third or rear series of air-heating fines utilizing the space in the rear of the furnace and producing the more perfect coinbustion of .the fire-gases generated in the furnace.

In the accompanying drawings, Figure 1 represents in part a front elevation and in 0 part a vertical transverse section of my improved regenerative gas-furnace. Fig. 2 represents horizontal sections of the same on lines :0 a: and 3 1 Fig. 1; and Figs. 3 and 4 represent vertical transverse sections, respectively, on

5 lines 2 z and k k, Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the combustion-chamber of my regenerative gasfurnace, which combustion-chamber is arranged below the gas-retorts, which are arranged symmetrically to the vertical axis of grate.

(No model.)

the furnace, as customary in a bench of gasretorts. In the ash-pit below the grate A is arranged a waterpan, A which serves to receive the ashes, so as to prevent the dust from the same from passing to the outside, and also to supply a certain quantity of moisture to the heated air conducted to the fuel on the At each side ofthe combustionchamber A, and on a lcvcl,or nearly so,with the grate A, is arranged a primary series of horizontal airflues, B B, which communicates at the front end with an opening, I), in the front wallofthe furnace, so as to (lILWJll the air, heat it in its passage through the lines B B, and conduct it through lateral eduction-channels 1) into the space below the grate A, as shown in Fig. 1. This primary series of air-flues B is heated up by smoke-fines O O 01, of which the fines O are arranged above and the bottom fines, O 0 below the air flues B B, and through which the products of combustion are conducted off from the top part of the furnace to the chimney O.

A second series of air-fines, D, is also arranged at each side of the combustionchamber A and at some distance above the grate A, the second series of air-flues receiving, like the first series, atmospheric air through openings (l in the front wall of the furnace, drawing the same through the dues D D, as shown in. Fig. 2, and emitting it in heated state through the lateral eduction-channels d to the upper part of the combustion chamber A, where the heated air mingles with the fire-gases gcneu ated by the incomplete combustion of the fuel on the grate and produces the combustion of the same. The air passing through the second series of air-fines D is heated in the same manner as the air in the primary series by means of flucs D above and lines D" below the air-fines D, through which heating-fines D D the products of combustion pass from the upper part'of the furnace on their way to the lower heating-Hues, O G O, and the chimney lines 0. The rctorts It are supported in the usual manner by bridge and saddle tiles, the spaces between said supporting-tiles permitting the fire-gases to pass freely around the retorts, so as to heat up the same.

The arrangement of a primary series of air flues for heating the air supplied to the fuel on the grate and the arrangement of a second series of air-fines above the first series for prodncing the combustion of the fire-gases at the upper partof the combustion-chamber are well known and form no part of the present in vention, which consists more especially in the arrangement of a third series of air-heating fines, E, at the middle rear part of the furnace back of the combustion-chamber A, as shown in Figs. 2 and 4.

The third series of air-fines, E, receives its air supply from openings 6 c in the front wall of the furnace, said openings being eonnccted by downwardly-extending flues e 6 with longitudinal fines e 0 below the ash-pit, which latter extend through the base of the rear wall of the combustion-chamber and connect with vertical channels 9 and the third series of horizontal fines, E, where the air is heated by radiation from the rear wall and finally conducted through an upwardlyex tending fine, e, and ednction-openings e, located at the upper front part of the fine 6" at a point between the first and second tier of retorts, into the furnace, as shown in Figs. 1 and 4. The additional quantity of heated air supplied by the third series of air-fines mingles with the unconsnmed fire-gases at the upper rear part of the furnace and burnsthe same, which has the effect of producing the still more complete combustion of the firegases and of heating up the rear ends of the retorts, where heretofore the perfect utilization of the fire-gases could not be secured,owing to the smaller depth of the combustionchamber.

A further advantageof the third series of air-heating fines arranged at the rear part of the furnace is that the space back of the combustion-chamber is utilized and the heat at the upper rear part of the furnace inereased,where heretofore the combustion was not going on as briskly as at the middle and front portions of the same.

Another and very important advantage of my improved gas-furnace is that the same has but a small depth below the floor andthat it combines compactness of construction with a high degree of economy in the consumption of fuel.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a regenerative gas-furnace, the comloination of a centralcombustion-chamber, a

primary series of air-heating fines at each side of the same, channels for supplying heatedair to the grate, a second series of air-heating fines arranged above the first series, lateral channels for conducting the air heated in said fines to the upper part of the combustionchamber, smoke-fines located above and below the primary and secondary series of air-fiues, a third series of horizontal air-heating fines arranged at the rear part of the furnace, back of the combustion-chamber, air-fines connecting-the bottom horizontal line of said third series of air-fines with the front wall of the furnace, and a vertical channel connecting the top horizontal fine of said third series of air-heating fines with the upper rear part of thefurnace above the eduction-channels of the second'series of air-heating fines and the firsttierof retorts, substantially as set forth.

2. In a regenerative gas-furnace, the combination, with the combustion-chamber, of a series of horizontal air-heating flues arranged back of the combustion-chamber at the rear part of the furnace, air-fines below the ash-pit for supplying air to said air-heating fines, and an upwardly-extending fine communicating with the air-heating fines and provided with an eduction-channel at its upper end above the first tier of retorts for discharging the heated air at the upper rear part of the furnace, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
